Spawn spot is at the top of the waterfall at the quest marker (52.7,31.4), located approximately above the R of Nar'thalas Academy on the World Map.

On spawning, the Rainha Peixe-rainha will commence to patrol northwards up the stream, continuing under the bridge and up to the northern waterfall (54.6,27.2). Then return back to the original spawn spot and repeat until engaged.

There tends to be withered standing near each whelpling, which would work well, except...-It is a world quest so it is crowded.-No matter how many crystals you pick up you can only help on whelpling. -Which means that by the time you kill the whithered, someone else will have helped the whelpling.

You have to kill a whithered (or collect the crystal from the ground) and then move to a new whelpling (in which case you will agro more whithered and have to kill them).

Of course Blizzard could have make the whelplings sharable, but that would be too easy.
